Polyethylene glycol is non-toxic and has excellent water solubility, solubility, lubricity, adhesion and thermal stability. Therefore, as a lubricant, dispersant, adhesive, excipient, etc., widely used in medicine, veterinary medicine and cosmetics industry.

Polyethylene glycol monostearate (PEG) is a kind of non-ionic surfactant, which is an indispensable raw material in daily industrial production. The main reason is that polyethylene glycol monostearate has the advantages of high emulsification ability, low foam and good wettability. It is widely used in printing emulsions and cosmetic emulsions.

Methoxy polyethylene glycol (PEG), as the starting material of one end of the decorative polyoxyethylene compound, is used in the pharmaceutical field, especially for chemical decoration of some physiologically active proteins such as peptides and enzymes. The compound is also used in drug delivery systems to chemically modify liposomes, polymer capsules, etc.

Polyethylene glycol products can be divided into pharmaceutical grade, cosmetic grade and industrial grade. Polyethylene glycol is widely used because of its excellent properties such as water solubility, non-volatility, physiological inertia, mild and lubricity.
